RAILWAY-RAIL JOINT.

Application filed March 18, 1918.

To all whom it may concern:

Be it known that I, JOHN HENRY Koss- MANN, a citizen of the UnitedStates, residing at St. Louis, in the State of Missouri, have inventedcertain new and useful Improvements in Railway-Rail Joints, of which thefollowing is a specification containing a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

My invention relates to an improved railway-rail joint, and consists inthe novel construction hereinafter described, and as particularlypointed out in the claim found at the end of this specification. V

The object of my invention is to increase the durability of railwayrails at the joints thereof, by providing a very strong reinforcing andsupporting construction for the rails at the joints; and a constructionwhich will be simple and inexpensive in manufacture and use; whereby therails will be prevented from being broken, and their life will belengthened, resulting in economy and durability.

In the drawings,

Figure 1 is a vertical transverse section of my improved rail-joint, I

Fig. 2 is a simialr section, showing a slight modification, and

Fig. 3 is a side elevation of the joint.

The numeral 1 designates the common rails to be joined, and they may (ofcourse) be of any well known form now in use upon the railways of thiscountry, whether steam, electric, or street-railway rails.

The ends of the said rails 1 abut upon and are supported by a horizontalbase-flange 2 formed integral with the lower edge of an outer fish-plate3, and said base-flange is itself supported by an underlying baseflange4: of an inner fish-plate 5, formed integral with the lower edge of thelatter.

'Io firmly secure the two fish-plates 3 and 5 and their base flanges inposition toclamp the rail-ends between said plates, as well as to lockthe said flanges in the position shown and described, I provide aplurality of separate and independent tie-plates 6 having raised flanges7, which are sufficiently Specification of Letters Patent.

high to form shoulders or abutments against which the said overlappingparts hear, so that (even without the usual spikes) the rails and thefish-plates will be held securely in the position shown.

The said independent tie-plates 6 are heavy and solid castings, or arerolled or stamped out of metal in an integral solid piece, so as toafiord a strong and unyielding bearing for the parts upon the separateties 9, and being (as they are shown) separate and independent eachtie-plate may be adjusted in its position beneath the base flanges ofthe fish-plates, to suit the space between adjacent ties, Whether it begreater or less within the limit of the length of said base flanges.

However, to make the, construction still more secure, reliable andpermanent, I pass through apertures in the overlying parts of saidfish-plates 3 and 5, base-fianges 2 and 4C, and the said tie-plate 6, anumber of the usual spikes 8, which latter may be either driven orscrewed into the ties 9 after being passed through the said apertures.

In the modification, shown in Fig. 2, both of the fish-plates 3 and 5are provided with integral base-flanges 10 in the same horizontal plane,and the inner edges of which flanges almost meet at a point beneath thecentral longitudinal line of the said rails 1, and the opposite baseflanges both rest directly upon the said tie-plate 6, and are locked inposition by the said flanges 7 near the opposite marginal edges of thesaid tielate.

P A further modification, which is especially designed for use uponstreet-railway grooved rails, is an integral upward extension 11 of theupper edge of the outer fish-plate 3, designed to afford thereat astrong brace or reinforcement for the head of the rail with which itrests in contact. (See Fig. 2.)

I claim:

An improved railway-rail joint, comprising two opposite fish-plateshaving integral base-flanges at their lower edges; the abutting ends oftwo rails, located upon and supported by the said base-flanges; twosolid separate unyielding tie-plates having opposite abutments Which arehigh enough to In testimony whereof I have signed my prevent spreachngof the base-flanges and name-t0 thls specificatlon in presence of twoform beanngs against which the outer edges subscrlbing wltnesses.

of said base-flanges rest; and spikes passing JOHN HENRY KO SSMANN. 5through registering apertures formed in the WVitnesses:
